JavaScript Left shift In the left shift operator <<, the left operand specifies the number and the right operand specifies the number to be shifted left. Zero bits are added to the right and excess bits from the left are discarded. One bit left shift in JavaScript For example, let a =...

The << operator shifts the bits of expression1 left by the number of bits specified in expression2. The data type of expression1 determines the data type returned by this operator. The << operator masks expression2 to avoid shifting expression1 by too much. Otherwise, if the shift amount ...

For example, a byte contains 8 bits; applying this operator to a value whose bit pattern is "00000000" would change its pattern to "11111111". The signed left shift operator "<<" shifts a bit pattern to the left, and the signed right shift operator ">>" shifts a bit pattern to the...
There are two shift operators in C++ programming: Right shift operator >> Left shift operator << 5. C++ Right Shift Operator The right shift operator shifts all bits towards the right by a certain number of specified bits. It is denoted by >>. When we shift any number to the right, th...
